Dear statalist.
I have fairly large asymmetric matrices (e.g. 200 by 200) from which I want to compute eigenvalues using the command:
matrix eigenvalues r c = A
Each of my asymmetric matrices are stored as separate .dta files and have the following general structure:
A B C D
A 0 0 1 0
B 2 0 0 1
C 3 1 0 2
D 1 0 2 0
How do I define each of these .dta files as the asymmetric matrix A so that Stata understands that the matrix in the .dta file is in fact an asymmetric matrix? As far as I can see, I need to do this in order to execute the command: matrix eigenvalues r c = A
Is there a simple command/way to accomplish this?
Thank you and kind regards,
Erik.
